In gathering data procedures, it should be noted that error control, the control gathering error in data is undertaken by two modes, respectively gathers selection and the placement data acquisition method of position data.
The selection gathering position data is to ensure that azimuthal correct basis.Analyze the characteristic of position location data, draw for two anchor points, when latitude is equal: longitude is every 0.00001 degree, and distance differs about 1 meter；Every 0.0001 degree, distance difference about 10 meters；Every 0.001 degree, distance difference about 100 meters；Every 0.01 degree, distance difference about 1000 meters；Every 0.1 degree, distance differs about ten thousand metres.And for two anchor points, when longitude is equal: latitude is every 0.00001 degree, and distance differs about 1.1 meters；Every 0.0001 degree, distance difference about 11 meters；Every 0.001 degree, distance difference about 111 meters；Every 0.01 degree, distance difference about 1113 meters；Every 0.1 degree, distance difference about 11132 meters.
Feature according to above position location data, present invention employs according to measuring basic point and measuring from the distance between point, it is determined that the mode of location data span solves the problem that data are selected.Concrete grammar is as follows:

In one embodiment, it is possible to determine positive north coordinate points according to measuring basic point and measurement from point；Straight line through described measurement basic point and described positive north coordinate points is defined as positive north datum line.
Although it should be noted that with the coordinate points name of positive north, but the concept in positive north being relative, in the embodiment of the present invention, the latitude of positive north coordinate points can more than the latitude measuring basic point, it is also possible to less than the latitude measuring basic point.Determining that positive north coordinate points is for the ease of calculating, those skilled in the art can determine positive north coordinate position according to practical situation.
In one embodiment, it is possible to making the line of a connection north and south poles in the position measuring basic point as positive north datum line, positive north, sensing due south, one end are pointed in this datum line one end, positive north, choose a bit as positive north coordinate points on the datum line of positive north.
In one embodiment, calculate in order to convenient, when determining positive north coordinate points, it is possible to measure basic point according to deflection and measure from point, formulate positive north coordinate points.Now, the determination principle of positive north coordinate points is to measure basic point for origin, and the longitude information of positive north coordinate points is equal to the longitude information measuring basic point.The latitude information of positive north coordinate points is set from point according to measuring.
For example, measuring basic point is A=A (NA, EA), measure from putting as B=B (NB, EB), positive north coordinate points N=N (Nn, En), work as NA>NBTime, the latitude value selection standard of positive north coordinate points is Nn≤NA；Work as NA<NBTime, the latitude value selection standard of positive north coordinate points is Nn≥NA。
In order to facilitate calculated direction angle, the latitude coordinate of positive north coordinate points is equal to the latitude information measured from point, and the longitude coordinate of positive north coordinate points is equal to the longitude information measuring basic point.That is: positive north coordinate points N=N (Nn, En)=N (NB, EA), measurement basic point, measurement are being attached mutually from point and positive north coordinate points, it will eight kinds of situations occur.Fig. 5 A～Fig. 5 D illustrates the schematic diagram of the determination just north coordinate points of one embodiment of the invention.As shown in Fig. 5 A～Fig. 5 D, N in Fig. 5 AB>NA, EB>EA, N in Fig. 5 BB<NA, EB>EA, N in Fig. 5 CB<NA, EB<EA, N in Fig. 5 DB>NA, EB<EA。

a2=(Nn-NB)2+(En-EB)2；
b2=(Nn-Na)2+(En-Ea)2；
c2=(Na-NB)2+(Ea-EB)2；
By the computing rule of trigonometric function, it is possible to obtain ∠ a=arccos ((b2+c2-a2)/2bc)*180/π。
In one embodiment, ∠ n, ∠ a and ∠ b form right angled triangle, ∠ b=90 ° of ∠ of a+ ∠ n=90 °, then can obtain ∠ a=arccos (b/c) * 180/ π=arcsin (a/c) * 180/ π.
Although it should be noted that to measure basic point A=A (NA, EA) and measure from a B=B (NB, EB) determine positive north coordinate points, but the invention is not restricted to this, those skilled in the art can select positive north coordinate points according to practical situation, for instance can also select on the datum line of positive north that other point is as positive north point, as long as being capable of the angle determining described measurement line with positive north datum line.And to measure basic point for initial point, it is only one embodiment of the present invention, in one embodiment, with longitude and latitude for the coordinate system of transverse and longitudinal coordinate, to measure from point for zero, or other can also being selected to measure point for zero, its principle is identical, calculate process by simple transformation, all can obtain antenna directional angle.
In one embodiment, after calculating measurement line north angle, the deflection of antenna level is calculated according to the relation measuring basic point with measure from point.After determining this measurement line north angle according to measurement line and positive north coordinate points, connecting measurement basic point A and measure from a B as measuring line, antenna horizontal direction angle is vertical with measuring line, and the direction sensing of antenna is anti-in coordinate points side, positive north.
According to measuring basic point and measuring the deflection calculating antenna level from the comparison put.Concrete grammar is as follows: measure basic point A=A (NA, EA), measure from a B=B (NB, EB), work as EA<EBTime, and NA<NBTime, antenna horizontal direction angle=90 °+∠ a or antenna horizontal direction angle=180 °-∠ b, orientation angle interval is: 90 ° of < < 180 ° of antenna horizontal direction angles.
